Microbial lipid fermentation of Trichosporon cutaneum in high saline water
Abstract Fermentative production of microbial lipid requires high fresh water input. The utilization of high saline seawater or industrial wastewater is an important alternative to reduce the freshwater consumption. This study revealed that oleaginous yeast Trichosporon cutaneum was tolerant to a hi...
